We know that in A.P series
18th term = a + 17d
29th term = a + 28d
But given
a + 17d = 29..........(i)
a + 28d = 18......... (ii)
Solving equation (i) and (ii), we get
d = -1
put d = -1 in any of the above equations and we get,
a = 46
Now, we know 49th term can be written as, a + 48d
putting the value of a and d in the above equation,
a + 48d = 46 + 48(-1)
= 46 - 48
= -2
Hence, the 49th term is -2.
Only '48' is not square of any number.
Carom is an indoor game.
3781 is the odd one out as other numbers contain only odd digits.
First indicates the lack of the second.
Conclusions:
All others are two in number.
F < E < J ? H > Z H ? Y and Z < H
As study of 'Brain ' is called 'Neurology', similarly, 'study' of Body is called 'physiology'.
A and C cannot be part of the same team since F has to be always selected with C but never with A.
as we don't know the gender of L.
